Abstract: A power conversion system utilizes an inductive device having a magnetic core formed of a plurality of wires that extend through the inductive device, and beyond its electric windings. The ends of the wires are formed around the electric windings, meet, and are connected together enveloping the magnetic core and windings forming a complete magnetic circuit. The inductive device may be a transformer used in a power supply, inverter, or other device with two or more windings, a choke coil with only one winding used in a ballast, power supply, inverter, or other inductive device. The power conversion system may further include a rectifier, a filter, and a regulator a so called analog system or components as in a switch mode system. In one embodiment of the power conversion system one or all of the rectification, filtering or regulation components or other components may be positioned within a housing formed by the magnetic core to provide physical protection and protection from the intrusion of electromagnetic interference from external sources.

Abstract: A stapler having a detached base supporting an anvil and a first magnetic element, and a stapling assembly for ejecting staples from a magazine port.  The stapling assembly supports a second magnetic element positioned for magnetic coupling to the base to align the anvil with the magazine port. Accordingly, the staple-driving stapling assembly and detached anvil-supporting base are not mechanically coupled. Instead, the stapling assembly and base are magnetically couplable. The magnetic coupling feature eliminates throat depth limitations and allows for staple placement at any desired location on a sheet of any size. An alignment guide may be provided to visually indicate an approximate location where a driven staple will be placed. The base and stapling assembly may be provided with friction pads for limiting movement of any sheets therebetween while stapling.

Abstract: Cette invention concerne une composition d'alliage métallique sans peau, exempte d'inclusions de gaz et comprenant des dendrites solides primaires dégradées et séparées, dispersées de façon homogène au sein d'une phase secondaire. On obtient cette composition métallique en chauffant l'alliage métallique dans un récipient jusqu'à sa liquéfaction (10). On fait ensuite refroidir rapidement le liquide tout en l'agitant (12) vigoureusement de manière à éviter les inclusions de gaz et à former des noyaux solides (14) répartis de manière homogène dans le liquide. L'agitation est arrêtée lorsque le liquide renferme une petite fraction solide ou que l'alliage liquide-solide est retiré de la zone d'agitation (12) cependant que l'on poursuit le refroidissement de lanière à obtenir les dendrites solides primaires dégradées séparées dans la phase secondaire liquide. Le mélange solide-liquide peut alors être formé, par exemple par coulage.

Abstract: The present invention is directed to a method of controlling a communications link and apparatus configured to perform this method. This invention is particularly related to but in no way limited to MIMO (multiple inputs multiple outputs) wireless communications systems. The method comprises the steps of determining at the receiver the quality of the communications link and based on this, selecting a group of transmission parameters and an element from this group.  These selections are then communicated to the transmitter. The transmission parameter may be the transmission configuration such as the modulation and coding scheme. The invention minimises the required feedback signalling from the receiver to the transmitter by exploiting temporal correlation of the parameter being controlled, whilst allowing rapid selection of the parameter.

Abstract: A bidirectional vibratory feeder for transporting objects in a curved path has a trough assembly including an elongated, generally horizontal bed defining the curved path, and a center of gravity. Resilient isolators are connected to the trough assembly and adapted to isolate the trough assembly from underlying terrain. An exciter mass assembly includes an exciter frame and a vibration generator coupled to the exciter frame for generating vibratory forces, the exciter mass assembly having a center of gravity. At least one horizontally disposed resilient coupling is connected between the exciter mass assembly and the trough assembly, and at least one vertically disposed link is connected between the exciter mass assembly and the trough assembly. The vibratory forces generated by the vibration generator include a vertical component directed along a substantially vertical path that passes through a combined center of gravity of the trough assembly and the exciter mass assembly that is transferred by the at least one vertically disposed link to cause each point on the trough assembly to translate vertically upward. The vibratory forces also include a horizontal component that is transferred by the at least one horizontally disposed resilient coupling to cause each point on the trough assembly to rotate along a path lying on an arc of a circle in a horizontal plane. The vibration generator is operable in at least first and second modes, wherein, in the first mode, the horizontal component. of the vibratory forces is directed along a first linear path displaced from the combined center of gravity to advance the objects in a first direction along the curved path and, in the second mode, the horizontal component of the vibratory forces is directed along a second linear path displaced from the combined center of gravity to advance the objects in a second, generally opposite direction along the curved path.
